The Bheptomino is a very common methuselah that evolves into three blocks, two gliders and a ship after 148 generations. Compare with Herschel, which appears at generation 20 of Bheptomino's evolution. It often arises with the cell at top left shifted one space to the left, which does not affect the subsequent evolution. Bheptominoes acquired particular importance in 1996 due to David Buckingham's work on B tracks.
It is considered a failed spaceship, but can be used to make a puffer 2.
In other rules
The Bheptomino is a stable puffer in many rules.
 In B3/S23e4e, it evolves into a (16,5)c/74 oblique spaceship.
 In B3/S23a, it is a glidesymmetric 10c/20 spaceship.
 In B34ej5y6n/S23, it is an oblique quadratic replicator, one of only a few known.
 In B36n/S2i36c7c, it evolves into a glidesymmetric 9c/70 diagonal spaceship.
